Hi Vineet, Interoperability enables you to preserve and take advantage of existing investments in unmanaged code. Code that runs under the control of the common language runtime (CLR) is called managed code , and code that runs outside the CLR is called unmanaged code . COM, COM+, C++ components, ActiveX components, and Microsoft Win32 API are examples of unmanaged code. Please refer the below link http://www.thebestcsharpprogrammerintheworld.com/fundamentals/interoperability.aspx Thanks

As all .NET language compilers produce Common Intermediate Language (CIL), then it is possible for different languages to interoperate with each other. For example a C# executable could use a class library written in VB.NET. For an example of this, check out this article: http://www.c-sharpcorner.com/uploadfile/cd3aa3/language-interoperability/ It is also possible for C# to interoperate with unmanaged code. There are two mechanisms for this: 1. COM interop for interoperating with COM servers such as Microsoft Office. 2. Platform Invoke (DllImport attribute) for interoperating with other unmanaged dlls, such as the Win32 API.
